Use of rapamycin and agents that inhibit B7 activity in immunomodulation
The invention provides methods for downmodulating an immune response comprising contacting immune cells from a subject with at least one agent that binds to at least one B7 molecule in combination with a Rapamycin compound.
1 . A method for downmodulating an immune response comprising contacting immune cells from a subject with at least one antibody that binds to at least one B7 molecule in combination with a Rapamycin compound.
2 . The method of claim 1 , wherein the cells are contacted with two antibodies that bind at least two different B7 molecules.
3 . The method of claim 1 , wherein the step of contacting is performed ex vivo.
4 . The method of claim 1 , wherein the step of contacting is performed in vivo.
5 . A method for downmodulating an immune response in a subject having an autoimmune disorder comprising contacting immune cells from the subject with at least one antibody that binds to at least one B7 molecule in combination with a Rapamycin compound.
6 . The method of claim 5 , wherein the immune cells are contacted with two antibodies that bind at least two different B7 molecules.
7 . The method of claim 6 , wherein the autoimmune disorder is systemic lupus erythematosis.
8 . A method for downmodulating an immune response in a subject suffering from systemic lupus erythematosis comprising administering to the subject an antibody that binds to B7-1, an antibody that binds to B7-2, and a Rapamycin compound, wherein the antibody that binds to B7-1 and the antibody that binds to B7-2 are administered over at least one short course of therapy.
9 . A method for downmodulating an immune response in a subject suffering from systemic lupus erythematosis comprising administering to the subject an antibody that binds to B7-1, an antibody that binds to B7-2, and a Rapamycin compound, wherein the Rapamycin compound is administered over at least one intermediate course of therapy.
10 . A method for downmodulating an immune response in a subject suffering from systemic lupus erythematosis comprising administering to said subject an antibody that binds B7-1, an antibody that binds B7-2, and a Rapamycin compound, wherein said Rapamycin compound is administered over at least one extended course of therapy.
11 . A method for downmodulating an immune response in a subject suffering from systemic lupus erythematosis comprising administering to said subject an antibody that binds B7-1, an antibody that binds B7-2, and a Rapamycin compound, wherein said Rapamycin compound is administered according to an early dosing regimen.
12 . A method for downmodulating an immune response in a subject suffering from systemic lupus erythematosis comprising administering to said subject an antibody that binds B7-1, an antibody that binds B7-2, and a Rapamycin compound, wherein said Rapamycin compound is administered according to a late dosing regimen.
13 . A method for downmodulating an immune response in a subject suffering from systemic lupus erythematosis comprising administering to said subject an antibody that binds B7-1, an antibody that binds B7-2, a Rapamycin compound, and an immunosupressing agents, wherein said immunosupressing agent is selected from the group consisting of FK506, Cyclosporin A and cyclophosphamide.
